+<dd><p>Build a <code>GIMPLE_ASSIGN</code> statement.  The left-hand side is an lvalue
+passed in lhs.  The right-hand side can be either a unary or
+binary tree expression.  The expression tree rhs will be
+flattened and its operands assigned to the corresponding operand
+slots in the new statement.  This function is useful when you
+already have a tree expression that you want to convert into a
+tuple.  However, try to avoid building expression trees for the
+sole purpose of calling this function.  If you already have the
+operands in separate trees, it is better to use
+<code>gimple_build_assign</code> with <code>enum tree_code</code> argument and separate
+arguments for each operand.

+<dd><p>This function is similar to two operand <code>gimple_build_assign</code>,
+but is used to build a <code>GIMPLE_ASSIGN</code> statement when the operands of the
+right-hand side of the assignment are already split into
+different operands.
+</p>
+<p>The left-hand side is an lvalue passed in lhs.  Subcode is the
+<code>tree_code</code> for the right-hand side of the assignment.  Op1, op2 and op3
+are the operands.
